Pull drm updates from Dave Airlie: "Highlights: - AMD KFD driver merge This is the AMD HSA interface for exposing a lowlevel interface for GPGPU use. They have an open source userspace built on top of this interface, and the code looks as good as it was going to get out of tree. - Initial atomic modesetting work The need for an atomic modesetting interface to allow userspace to try and send a complete set of modesetting state to the driver has arisen, and been suffering from neglect this past year. No more, the start of the common code and changes for msm driver to use it are in this tree. Ongoing work to get the userspace ioctl finished and the code clean will probably wait until next kernel. - DisplayID 1.3 and tiled monitor exposed to userspace.

In order to support the "enable GPIO" available in many panel devices, this commit adds a proper devicetree binding.

2014-09-10drm: add driver->set_busid() callbackDavid Herrmann1-0/+1
One step closer to dropping all the drm_bus_* code: Add a driver->set_busid() callback and make all drivers use the generic helpers. Nouveau is the only driver that uses two different bus-types with the same drm_driver. This is totally broken if both buses are available on the same machine (unlikely, but lets be safe). Therefore, we create two different drivers for each platform during module_init() and set the set_busid() callback respectively.

2014-07-08drm/tilcdc: remove submodule destroy callsGuido Martínez6-53/+50
The TI tilcdc driver is designed with a notion of submodules. Currently, at unload time, these submodules are iterated and destroyed. Now that the tilcdc remove order is fixed, this can be handled perfectly by the kernel using the device infrastructure, since each submodule is a kernel driver itself, and they are only destroy()'ed at unload time. Therefore we move the destroy() functionality to each submodule's remove(). Also, remove some checks in the unloading process since the new code guarantees the resources are allocated and need a release.

This can save 5 or 6W on some optimus laptops. - drm core: combined GEM and TTM VMA manager per-filp mmap permission tracking initial rendernode support (via a runtime enable for now, until we get api stable), remove old proc support, lots of cleanups of legacy code hdmi vendor infoframes and 4k modes lots of gem/prime locking and races fixes async pageflip scaffolding drm bridge objects - i915: Haswell PC8+ support and eLLC support, HDMI 4K support, initial per-process VMA pieces, watermark reworks, convert to generic hdmi infoframes, encoder reworking, fastboot support, - radeon: CIK PM support, remove 3d blit code in favour of DMA engines, Berlin GPU support, HDMI audio fixes - nouveau: secondary GPU power down support for optimus laptops, lots of fixes, use MSI, VP3 engine support - exynos: runtime pm support for g2d, DT support, remove non-DT, - tda998x i2c driver: lots of fixes for sync issues - gma500: lots of cleanups - rcar: add LVDS support, fbdev emulation, - tegra: just minor fixes" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (684 commits) drm/exynos: Fix build error with exynos_drm_connector.c drm/exynos: Remove non-DT support in exynos_drm_fimd drm/exynos: Remove non-DT support in exynos_hdmi drm/exynos: Remove non-DT support in exynos_drm_g2d drm/exynos: Remove non-DT support in exynos_hdmiphy drm/exynos: Remove non-DT support in exynos_ddc drm/exynos: Make Exynos DRM drivers depend on OF drm/exynos: Consider fallback option to allocation fail drm/exynos: fimd: move platform data parsing to separate function drm/exynos: fimd: get signal polarities from device tree drm/exynos: fimd: replace struct fb_videomode with videomode drm/exynos: check a pixel format to a particular window layer drm/exynos: fix fimd pixel format setting drm/exynos: Add NULL pointer check drm/exynos: Remove redundant error messages drm/exynos: Add missing of.h header include drm/exynos: Remove redundant NULL check in exynos_drm_buf drm/exynos: add device tree support for rotator drm/exynos: Add missing includes drm/exynos: add runtime pm interfaces to g2d driver ...

2013-08-23i2c: move OF helpers into the coreWolfram Sang2-2/+0
I2C of helpers used to live in of_i2c.c but experience (from SPI) shows that it is much cleaner to have this in the core. This also removes a circular dependency between the helpers and the core, and so we can finally register child nodes in the core instead of doing this manually in each driver. So, fix the drivers and documentation, too. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

2013-08-19drm: remove FASYNC supportDaniel Vetter1-1/+0
So I've stumbled over drm_fasync and wondered what it does. Digging that up is quite a story. First I've had to read up on what this does and ended up being rather bewildered why peopled loved signals so much back in the days that they've created SIGIO just for that ... Then I wondered how this ever works, and what that strange "No-op." comment right above it should mean. After all calling the core fasync helper is pretty obviously not a noop. After reading through the kernels FASYNC implementation I've noticed that signals are only sent out to the processes attached with FASYNC by calling kill_fasync. No merged drm driver has ever done that. After more digging I've found out that the only driver that ever used this is the so called GAMMA driver. I've frankly never heard of such a gpu brand ever before. Now FASYNC seems to not have been the only bad thing with that driver, since Dave Airlie removed it from the drm driver with prejudice: commit 1430163b4bbf7b00367ea1066c1c5fe85dbeefed Author: Dave Airlie <airlied@linux.ie> Date: Sun Aug 29 12:04:35 2004 +0000 Drop GAMMA DRM from a great height ... Long story short, the drm fasync support seems to be doing absolutely nothing. And the only user of it was never merged into the upstream kernel. And we don't need any fops->fasync callback since the fcntl implementation in the kernel already implements the noop case correctly. So stop this particular cargo-cult and rip it all out. v2: Kill drm_fasync assignments in rcar (newly added) and imx drivers (somehow I've missed that one in staging). Also drop the reference in the drm DocBook. ARM compile-fail reported by Rob Clark. v3: Move the removal of dev->buf_asnyc assignment in drm_setup to this patch here. v4: Actually git add ... tsk.

2013-08-19drm/tilcdc fixup mode to workaround sync for tda998xDarren Etheridge2-2/+32
Add a fixup function that will flip the hsync priority and add a hskew value that is used to shift the tda998x to the right by a variable number of pixels depending on the mode. This works around an issue with the sync timings that tilcdc is outputing.

2013-08-07drm/gem: create drm_gem_dumb_destroyDaniel Vetter1-1/+1
All the gem based kms drivers really want the same function to destroy a dumb framebuffer backing storage object. So give it to them and roll it out in all drivers. This still leaves the option open for kms drivers which don't use GEM for backing storage, but it does decently simplify matters for gem drivers.
